2.7 Winching and Towing Procedures
This
section provides the operator with procedures
about towing and winching and on how to manually
release the parking brake.
Warning
Ensure platform is fully lowered before winching or
towing. Sudden motion could cause the aerial
platform to become unstable.
Death or serious injury could result.
Warning
In emergency situations where machine functions
are not available and lowering is impeded by an
obstacle, the utmost care must be taken to move
the machine far enough to clear the obstacle. In
such cases operation must be extremely smooth
with no sudden movements and must not exceed
a speed of 2”/sec.
Warning
When pushing, towing or winching,
do not exceed 2 mph (3.2 km/h).
Warning
Do not push, tow or winch vehicle on to
a slope, or brake the towing
vehicle rapidly. Do not pull the aerial platform
down an incline towards a winch.
2.7-1 To Release the Parking Brake Manually
Figure 2-18. Parking Brake
Parking Brake
- The brake MUST be manually disen-
gaged for pushing, towing or winching.
Warning
Do not manually disengage the parking brakes
if the aerial platform is on a slope.
1.
Make sure that the aerial platform is on level
ground. Chock or block the wheels to keep aerial
platform from rolling.

to “OFF” position.

tow or winch the aerial platform to the desired
location.
5.
Position aerial platform on a firm level surface.
Chock or block the wheels to prevent the aerial
platform from rolling.
